Abstract: A media streamer includes at least one storage node including mass storage for storing a digital representation of at least one video presentation. The mass storage is comprised of a plurality of mass storage units. The at least one video presentation requires a time T to present in its entirety, and is stored as a plurality of N data blocks. Each data block stores data corresponding to approximately a T/N period of the video presentation. The media streamer further includes a plurality of communication nodes each having at least one input port that is coupled to an output of the at least one storage node for receiving a digital representation of a video presentation therefrom. Each of the plurality of communication nodes further includes a plurality of output ports individual ones of which transmit a digitalrepresentation as a data stream to a consumer of the digital representation. The N data blocks of the digital representation are partitioned into X stripes, wherein data blocks 1, X+1, 2*X+1, . . . etc., are associated with a first one of the X stripes, data blocks 2, X+2, 2*X+2, ... etc., are associated with a second one of the X stripes, etc., and wherein individual ones of the X stripes are each stored on a different one of the plurality of mass storage units. The plurality of mass storage units preferably store a single copy of a digital representation of a video presentation. The X stripes are read out in such a manner as to enable a plurality of data streams to simultaneously convey a same one of the N data blocks, or are read out in such amanner as to enable a plurality of data streams to simultaneously convey a different one of the N data blocks.

Title: Apparatus and method of decoding data groups of pictures
Inventor: NITTA HAJIME
IPC: H03M7/00
Filed: 1996-02-08
Abstract: Data decoding decodes data reproduced from a record medium and stored in a memory. Since decoding requires a sufficient amount of data to be stored in memory especially when the data is, for example, predictively encoded, a system controller is provided which inhibits previously read data from being overwritten in memory. Thus, when a reverse reproduction operation is suddenly initiated during a forward reproduction operation, a sufficient amount of data is reserved in the memory for decoding the data in the reverse direction. Similarly, the system controller inhibits the memory from writing over previously read data during a reverse reproduction and a sufficient amount of data is reserved for decoding when forward reproduction is resumed.

Title: Cathodically protected concrete article, anode, and process for production thereof
Inventor: MUMBY TIMOTHY ALAN
IPC: C23F13/00
Filed: 1996-02-26
Abstract: A concrete article reinforced with a ferrous material in said concrete article can be cathodically protected from corrosion by the application of a coating composite which can be applied, for instance, by thermally spraying a valve metal or alloy thereof together with a catalyst precursor compound onto a surface of said concrete article. Alternatively, the concrete article may be previously or subsequently coated with a catalyst precursor compound to form a separately layered anode coating. Conversion of the catalyst precursor compound to an electrochemically active catalyst occurs during thermal spraying or by the application of the thermally sprayed valve metal or alloy thereof over the previously applied catalyst precursor compound. Connecting the anode coating and the ferrous reinforcing material in the concrete structure to an electrical circuit and impressing a current sufficient to cause the ferrous material to act as the cathode in said circuit provides protection of the ferrous material against corrosion.
